Lewis base] was found to be a highly active and selective catalyst system in the [2+3] cycloaddition between epoxides and isocyanates to form 5-oxazolidinones. The reaction proceeds to high yield under mild reaction conditions and is applicable to a variety of terminal epoxides and aryl isocyanates.

Hit to lead optimization of (5R)-5-hexyl-3-phenyl-1,3-oxazolidin-2-one as a positive allosteric modulator of mGluR2 is described. Improvements in potency and metabolic stability were achieved through SAR on both ends of the oxazolidinone. An optimized lead compound was found to be brain penetrant and active in a rat ketamine-induced hyperlocomotion model for antipsychotic activity. (C) 2010 Elsevier Ltd. All rights reserved.
